GroupWise® enables you to retain user messages until they have been copied from message databases to another storage location. This means that a user cannot perform any action, such as emptying the mailbox Trash, that will result in a message being removed from the message database before it has been copied.
Message retention primarily consists of two activities: 1) not allowing users to remove messages until they have been retained and 2) retaining the messages by copying them from message databases to another location.
GroupWise supplies the ability to not allow users to remove messages until they've been retained. It also provides methods for message retention applications to securely access user mailboxes and copy messages. However, it does not provide the message retention application. You must develop or purchase a third-party (non-GroupWise) application that performs this service.
